attozvwi o I metal and also for the purpose of ineintiiinl plates and placed in position in the flask.

in the sections of the chill in their proper Fe etive position, I provide one of the tions such as 18 iiith a shoulder 1242, adapted o over-hang 21 correeponding shoulder formed on lhe section 19. 'lhcse interlocking shoulders are clearly shown in Fig. 5. Instead of the square shoulders: shown in this figure, I may, as illustrated in l3, employ a beveled face construetion. "hot is, A. may provide a. portion 2-? on die section 18 adapted to over-hang the face 25 formed on the section 19.

In order to form lhe casting with u nuinerzil indicating its weight, as indiculed zit r 17, Fig. l, I provide upon the conieul surface of one or both of the pin-ls oi the chill 2 ,9. numeral patleru, as indicated at 26, 2?,

which panlcrn may be either in reliel, or in I intaglio, lhe nun being shown in the d 21W- mg, to form a numeral 'in relief upon the casting. When then/"eight 1s cast the conicul core portions of the chill form an eye with inclined walls and the numerals are cast upondhese inclined walls. The numerals arelhus in a sort oi dcpl'csaion lll the casting, et a point where they inn he 1 easily seen and will not interfere with lhe operation of the Weight, and, being met. against the smooth surface of the chill the numerals stand out more clearly than if cue-l; in a sand mold.

'The method of forming the weights will be eppurent. The gate pattern 7 first placed in position as shown in Fig. 1 and. lhe sash weight pullcrns, such as ll and l2, are inserted through the openings in the end The enlire flask is then filled With'send and the sash.
